Frequency to Voltage Converter Circuit Frequency to voltage converter converts the frequencies or pulses to the proportional electrical output such as voltage or current. It is an important tool for electromechanical measurements where repeated events are occurring. So, when we provide a frequency across a frequency to voltage converter circuit, it will provide a proportional DC output. Here we are using KA331 IC… |

Hartley Oscillator In simple terms, the oscillator is a circuit which converts DC power from the supply source to the AC power to the Load. Oscillator system is built using both active and passive components and it is used for the production of sinusoidal or any other repetitive waveforms at the output without any application of an external input signal. We discussed few oscillators in our… |

An Overview of Dual Converters In the previous tutorial, we saw how a Dual Power Supply Circuit is designed. Now, we learn about Dual Converters, which can convert AC to DC and DC to AC at the same time. As the name suggests, Dual Converter has two converters, one converter works as a rectifier (Converts AC to DC) and the other converter works as an inverter (converts DC into AC). Both converters are… |

Colpitts Oscillator An oscillator is a mechanical or electronic construction which produces oscillation depending on few variables. We all have devices which need oscillators like a traditional clock or a wristwatch. Various types of metal detectors, computers where microcontroller and microprocessors are involved use oscillators, especially electronics oscillator which produces periodic… |

What is JFET: Its Construction, Working and Biasing Techniques JFET is a Junction gate field-effect transistor. A normal transistor is a current-controlled device which needs current for biasing, whereas a JFET is a voltage-controlled device. Similar to MOSFETs, as we have seen in our previous tutorial, JFET has three terminals: Gate, Drain, and Source. JFET is an essential component for precision-level voltage… |

What is MOSFET: Its Construction, Types and Working MOSFET is basically a transistor which uses field effect. MOSFET stands for Metal Oxide Field Effect Transistor, which has a gate. The gate voltage determines the conductivity of the device. Depending on this gate voltage we can change the conductivity and thus we can use it as a switch or as an amplifier like we use Transistor as a switch or as an amplifier. … |
